The CBSE Class 10 Maths Syllabus 2027 covers seven units and 14 chapters from the NCERT Mathematics textbook. CBSE offers two versions: Mathematics Standard (Code 041) for students planning to study Maths in Class 11, and Mathematics Basic (Code 241) for others. Both versions follow the same Class 10 maths syllabus but differ in difficulty level.
- Algebra carries the highest unit-wise weightage of 20 marks, covering Polynomials, Pair of Linear Equations, Quadratic Equations and Arithmetic Progressions.
- Geometry carries 15 marks and focuses on triangle similarity, the Basic Proportionality Theorem (BPT), and circle tangent theorems.
- Trigonometry carries 12 marks, while Statistics and Probability together account for 11 marks. Mensuration carries 10 marks, covering areas, surface areas, and volumes.
- The CBSE Class 10 Mathematics exam pattern includes MCQs, assertion–reason questions, short-answer questions, long-answer questions, and case-based questions.
- NCERT Mathematics textbooks should be the primary preparation resource, followed by additional practice from R.D. Sharma or R.S. Aggarwal, timed mock tests and revision of common calculation errors.

CBSE Class 10 Mathematics Preparation Tips 2027
With theory board exams in February–March 2027, you have approximately four to five months from October 2026 to cover the full syllabus and revise. Use the tips below to plan your preparation.
- Algebra (Unit II) carries 20 marks: Prioritize it above all other units. Cover Quadratic Equations, Pair of Linear Equations, and Arithmetic Progressions before moving to other units.
- Complete every NCERT exercise question. Board questions closely follow NCERT examples and exercise problems.
- Revise Geometry (Triangles and Circles) systematically: Proof-based questions of 4–5 marks appear every year.
- Attempt at least three full-length CBSE sample papers under timed conditions before January 2027.
- If you choose Mathematics Standard (Code 041), supplement NCERT with R.D. Sharma's exercises for higher-difficulty practice.
- For Standard Maths (041): Supplementing NCERT is crucial because around 20–25% of the paper tests high-level application and analytical skills. Focus on the solved examples and selected tricky problems in R.D. Sharma or R.S. Aggarwal.
As per students on Reddit, below are some tips to apply in your CBSE Class 10 board exam prep:
- Complete all NCERT exercises and solved examples. Solve NCERT Exemplar questions as many direct questions come from here (at least cover the MCQs if pressed for time).
- Solve at least 5 years of Previous Year Questions (PYQs) alongside Exemplar. Solve up to 5 sample papers to build time management and understand paper formatting.
